I bought this pressure gauge w/hose and insert for my pony bottle configuration. I had to assemble the gauge to the hose by placing the insert inside each piece. I felt a need to contact [...] support to make sure that I was doing it right. They confirmed what seemed logically correct to me. However, during my second dive with it to 110 fsw, a dive buddy noticed small bubbles coming from the gauge/hose connection. Back aboard ship, I disassembled the hose and gauge and coated appropriate parts of the insert with silicone grease and reassembled the pieces. The problem went away. I don't believe there were any assembly instructions with the gauge/hose/insert. I would have preferred that they were there with instructions to silicone grease the insert before inserting into the hose and gauge.

This pressure guage is cool for international travels, providing metric and imperial measure. However, this guage requires the seals be changed out a couple of times per year because the o rings fail regularly. I like the guage enough to tolerate its leaking, so I change the seals about once every 4 to 6 months and always carry the necessary wrenches and extra o rings becasue its gonna leak.

Durable and well built. I own several of these and all of them have several hundred dives on them over many years. One failed due to a leak in the case but other than that this is a reliable and well built instrument.
